FIELD OF THE INVENTION

The present invention relates to a field of packaging, and more particularly to a packaging device.

BACKGROUND OF THE INVENTION

According to the existing manufacturing process of a liquid crystal display, it generally includes the following steps:

Preliminary manufacturing process of array: making array substrate and the color filter substrate;

Intermediate manufacturing process of cell: marrying the array substrate and the color filter substrate, and gluing the two after filling liquid crystal between the array substrate and the color filter substrate, then dissecting the substrate into proper dimension for liquid crystal display panel;

Final manufacturing process of assembling module: the panel will then be assembled with other parts, such as a backlight module, printed circuit hoard, and frame etc so as to completely the assembly of a liquid crystal display.

During the above described manufacturing processes, after the those two substrates were married and filled with liquid crystal, and dissected, those individual panels have to be well packed so as to deliver to the next workstation for modulating thereby completing the manufacturing processes.
